图3为本申请实施例提供的一种头戴显示设备的音量调节装置的结构示意图。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请参照图1，图1为本申请实施例提供的一种头戴显示设备的音量调节方法的流程示意图。该方法包括：
S110：拾取用户入耳处的声音信号；
需要说明的是，本实施例中具体可以在接收到用户输入的开启自动调节指令后拾取用户入耳处的声音信号，其中，用户可以通过打开功能开关的方式输入自动调节指令，并且当用户通过头戴显示设备的喇叭收听声音时，可以通过预先设置在头戴显示设备上的、距离收听位置较近的位置处的第一MIC拾取用户入耳处的声音信号；当用户通过头戴显示设备的耳机收听声音时，可以通过设置在耳机前端的第二MIC拾取用户入耳处的声音信号。
具体的，可以通过检测用户当前的收听方式来确定用户通过喇叭还是耳机收听声音，然后再进一步控制对应的MIC拾取用户入耳处的声音信号。
S120：依据声音信号及当前播放的音频信号，获取声音信号中的环境声音信号；
需要说明的是，在拾取到用户入耳处的声音信号后，该声音信号包括两部分，一是头戴显示设备当前播放的音频信号通过耳机或喇叭的播放传输至人耳处的声音信号，另一种是环境声音信号，因此，可以根据头戴显示设备当前播放的音频信号从所拾取的声音信号中提取出环境声音信号。
S130：依据环境声音信号确定头戴显示设备的输出音量目标值；
具体的，在从所拾取的声音信号中提取出环境声音信号后，根据该环境声音信号确定出头戴显示设备的输出音量目标值，以便根据该输出音量目标 值对头戴显示设备的音量进行调节，也即使调节后的设备输出音量接近环境声音传输至人耳处的音量，从而可以避免用户因环境声音较大听不清设备播放的声音内容的问题。
进一步的，本实施例中的S130中依据环境声音信号确定头戴显示设备的输出音量目标值的过程，具体可以为：
获取环境声音信号在预设时长内的平均幅值；
依据平均幅值及预设关系式，得到输出音量目标值，其中：
预设关系式为β＝b+log
a(α+1)，其中，β表示输出音量目标值，b表示头戴显示设备的当前播放音量值，a为大于1的常量，α表示平均幅值。
具体的，本实施例中可以根据提取出的环境声音信号计算出预设时长内的平均幅值，例如计算出一帧内环境声音信号的平均幅值，具体可以用α表示，然后根据该平均幅值和预设关系式计算出输出音量目标值β，从而得到输出音量目标值。其中，预设关系式β＝b+log
a(α+1)中的输出音量目标值β随平均幅值α的变化曲线如图2所示。
需要说明的是，本实施例中的常量a为大于1的常量，并且该常量a满足头戴显示设备的伴音功率，也即在实际应用中可以预先根据头戴显示设备的伴音功率要求设置常量a。
进一步的，在依据环境声音信号确定头戴显示设备的输出音量目标值之前，该方法还可以包括：
依据环境声音信号确定环境声音大小；
当环境声音大小大于头戴显示设备的当前播放音量值预设值时，执行依据环境声音信号确定头戴显示设备的输出音量目标值的步骤。
具体的，本实施例中可以在确定出头戴显示设备的输出音量目标值之前，先根据环境声音信号确定出环境声音大小，并且将环境声音大小与头戴显示设备的当前播放音量值进行比较，当头戴显示设备的当前播放音量值大于环境声音大小，并且差值大于预设值时，再根据环境声音信号确定出头戴显示设备的输出音量目标值。也即，当环境声音大小与头戴显示设备的当前播放音量值相比，环境声音较大、且高出头戴显示设备的当前播放音量值预设值时，说明环境声音已经影响到用户对设备输出的声音进行收听，此时需要对头戴显示设备的音量进行调节，在调节之前需要确定出头戴显示设备的输出 音量目标值。
S140：依据输出音量目标值对头戴显示设备的音量进行调节。
具体的，在确定出输出音量目标值后，可以根据该输出音量目标值对头戴显示设备的音量进行调节，使调节后头戴显示设备的播放音量在达到人耳处时用户能够听到设备播放的声音，不再受环境声音的影响。
进一步的，上述S140中依据输出音量目标值对头戴显示设备的音量进行调节的过程，具体可以为：
调节头戴显示设备的音量从当前播放音量值逐渐变化至目标音量范围，目标音量范围为依据输出音量目标值得到的。
具体的，本实施例中在确定出头戴显示设备的输出音量目标值后，可以根据该输出音量目标值确定出目标音量范围，也即只要头戴显示设备的输出音量值在该目标范围内所播放的声音传输至人耳处时，用户就能够挺清楚设备播放的声音。因此，在确定出目标音量范围后，可以控制头戴显示设备的音量从当前播放音量值逐渐变化至该目标音量范围，其中，为了避免设备播放的声音突然变大引起用户的不适，可以使用户以渐变的方式由当前播放音量逐渐变化至目标音量范围，具体可以以线性变化的方式渐变至目标音量范围，当然还可以以曲线的方式进行渐变调节，具体方式可以根据实际情况进行确定，本实施例不做特殊限定。
可见，该方法可以通过拾取用户入耳处的声音信号，并根据当前播放的音频信号从该声音信号中提取出环境声音信号，并根据该环境声音信号确定出头戴显示设备的输出音量目标值，然后再根据该输出音量目标值进行音量调节，从而实现音量的自动调节，方便用户使用，提高用户使用体验。
在上述实施例的基础上，本申请实施例还相应的提供了一种头戴显示设备的音量调节装置，具体请参照图3。该装置包括：
拾取模块21，用于拾取用户入耳处的声音信号；
提取模块22，用于依据声音信号及当前播放的音频信号，获取声音信号中的环境声音信号；
确定模块23，用于依据环境声音信号确定头戴显示设备的输出音量目标值；
调节模块24，用于依据输出音量目标值对头戴显示设备的音量进行调节。
进一步的，确定模块23包括：
获取单元，用于获取环境声音信号在预设时长内的平均幅值；
计算单元，用于依据平均幅值及预设关系式，得到输出音量目标值，其中：
预设关系式为β＝b+log
a(α+1)，其中，β表示输出音量目标值，b表示头戴显示设备的当前播放音量值，a为常量，α表示平均幅值。
需要说明的是，本实施例在使用过程中具有与上述方法实施例相同的有益效果，对比本实施例中所涉及到的头戴显示设备的音量调节方法的具体介绍请参照上述实施例，本申请在此不再赘述。
在上述实施例的基础上，本申请实施例还提供了一种头戴显示设备的音量调节***，该***包括：
存储器，用于存储计算机程序；
处理器，用于执行计算机程序时实现如上述头戴显示设备的音量调节方法的步骤。
